It acknowledges receipt of the previous packet in the sequence.
TCP uses the acknowledgement number in segments sent back to the source to indicate the next byte in this session that the receiver expects to receive. This is called expectational acknowledgement.

The Transmission Control Protocol (TCP) is a core protocol of the Internet protocol suite. The sequence number and acknowledgement number are used to confirm receipt of data.
flow control
If the sending device does not receive an acknowledgement for a packet, the packet will be retransmitted.
TCP is a protocol that uses those.
The acknowledgement number is a crucial component in data communication protocols, particularly in TCP (Transmission Control Protocol). It serves to confirm the successful receipt of packets by the receiving device, allowing the sender to know which data has been received and which may need to be retransmitted. This mechanism helps ensure reliable data transfer and flow control, enhancing the overall integrity of the communication process.
Short for Round Tripp Time... It's the time a TCP packet takes to travel to it's destination and back (in the form of an acknowledgement-packet).

TCP Breaks User Data Into Segments, Numbers Each Segment, Places Them In The Correct Sequence, And Sends Each In Order, Waiting For An Acknowledgement Before Sending The Next Segment.
